A slab leak in Coats is a water line leaking under a concrete floor, and a plumber fixes it by repairing the spot through the slab or by running a new line above the floor. More than half of Coats' homes were built before 1980, which often makes replacing the old buried pipe the smarter choice. Call the number on this page to be connected with a local plumber in Coats.
What kind of house in Coats gets a slab leak?
One with pipe under concrete. Coats' median home was built in 1978, and about 55.3% of homes predate 1980, according to Census survey data. Older homes in eastern Harnett County were commonly built on crawl spaces, so many leaks under the floor can be reached from below. Slab leaks show up in ranch houses on grade, slab additions and garage conversions. If you aren't sure, look for foundation vents or a crawl space door.
Is my water causing the pipe to fail?
Probably not by itself. The Town of Coats buys Cape Fear River water from Harnett Regional Water and distributes it to about 970 customers, and the 2025 report lists both chlorine and chloramine residuals. In 2025 lead and copper sampling, neither lead nor copper was detected at the 90th percentile, and no homes were above action levels. Pipe under a slab usually fails from age, abrasion against concrete or stone, or damage when it was installed. A plumber can look at the failed section to judge the cause.
Who fixes what?
Pipe under your house is the owner's responsibility. The town's sources we found don't say exactly where its responsibility for a service line ends, so if the leak seems to be at the meter or in the yard, call Coats Public Works first. The town has prepared a service line inventory you can request. For the leak itself, a plumber will pressure test the lines, pinpoint the spot, and recommend either a slab repair or a reroute through walls, the attic or a crawl space.
In an older house, ask about the rest of the line, too. If the pipe near the leak shows thinning or corrosion, fixing one spot may only buy time. Replacing the buried run in one job usually costs less than coming back for a second and third leak, and it leaves the slab alone if the new pipe goes overhead.
Coats permit note
Plumbing permits and inspections in Coats go through Harnett County Inspections, but the county won't issue a building permit until the Town grants a zoning permit. The plumber can tell you what your repair requires.
